摘要： The present invention provides an electromagnet device including a horizontal portion of a yoke arranged near one end portion of an iron core, a movable iron piece which pivotably supported on a leading end edge portion of a vertical portion of the yoke which serves as a fulcrum, an end portion of the movable iron piece adapted to be attracted to a magnetic pole portion by a main magnetic circuit, the magnetic pole portion is arranged in the other end portion of the iron core. The main magnetic circuit is formed by applying a voltage to a coil wound around a periphery of the iron core and an auxiliary magnetic circuit formed in parallel with the main magnetic circuit, the auxiliary circuit including a permanent magnet is arranged near the one end portion of the iron core and a magnetic resistance portion, in which a magnetic flux of the permanent magnet is magnetically saturated.
